Question

which action can humans take to reduce wave erosion? build drainage systems build houses near coastlines build breakwaters in the ocean reduce vegetation along coastlines

Explanation:

• Drainage systems manage water flow on land, not wave erosion.
• Building houses near coastlines increases exposure to erosion, it does not reduce it.
• Breakwaters are structures placed in the ocean to block or dissipate wave energy, directly reducing erosion of shorelines.
• Reducing coastal vegetation removes natural protection against erosion, worsening the issue.

Answer:

build breakwaters in the ocean
